iPhone 5 Wi-Fi Problems Fixed By Manual DNS Settings
Some iPhone 5 users are experiencing a variety of issues with wifi on the device, almost always revolving around inconsistently slow wireless connections. If you’re having this problem, you’re not alone, and the good news is you can almost certainly get an immediate improvement by setting manual DNS on the device.
Fixing Slow iPhone 5 Wi-Fi With Manual DNS Settings
For the impatient, you can immediately try Google’s DNS services (18.104.22.168 or 22.214.171.124), but for the best results you’ll want to follow the full process to find the fastest DNS servers:
- Download NameBench on your Mac or PC and run it to discover the fastest DNS servers for your location, the test will take a few minutes
- Take the best result and grab your iPhone 5
- Open Settings, tap on “Wi-Fi”, and tap the blue arrow alongside the connected Wi-Fi network
- Tap next to “DNS” to manually adjust the DNS entry (Didn’t run NameBench? Try 126.96.36.199 or 188.8.131.52)
Leave Settings and try running Speed Test again, browse the web, or doing anything online with the iPhone 5 using the same wi-fi connection. Everything should be leaps and bounds faster.
Interestingly enough, we’ve been here before, and using custom DNS entries directly on the iPhone has fixed slow wi-fi issues in the past. With the same solution working again, it suggests it’s a compatibility issue with how the iPhone is interacting with certain routers. This would explain why not everyone experiences the problem, and why the same iPhone has issues on some networks but not others.
For iPhone 5 owners that have not experienced the wi-fi issue, basically it’s a lot slower with intermittent connectivity.
Give it a try, let us know how it works for you.
